Feature: 1. Solar Ultrasonic Spikes:Emit a beep sonic of 400Hz when vibrating every 30 seconds. The animal feels the sound and vibration highly irritating so flee from a certain area. 2. Solar Powered:Powered by a rechargeable solar cell, with charging rates of just 6-8 hours, for 5-7 days of use and up to 7000 sq ft of coverage. 3. Human and No mess:Be safe to use around pets and humans, no dispose of the body, it\u0027s safe for soil environment and nearby planting. 4. Waterproof and Durable:Waterproof and corrosion-resistant and ABS flame retardant material also apply to rainy days. Insert it into the soil, and make sure the top part is about 2 inches above the ground to avoid water flowing into the interior. Specification: Solar rodent repeller is a kind of rodent repeller that uses solar panels to charge the battery. It stimulates the nervous system and pain system of mice through the buzzer cycle vibration wave, so as to achieve the purpose of driving away rats. The rat repellent deteriorates the living environment of rats, reduces the activity and reproduction ability, and makes them degenerate to extinction naturally! The device can also drive away moles, snakes, ants, and harmful organisms Features: Solar Ultrasonic Spikes:Emit a beep sonic of 400Hz when vibrating every 30 seconds.
